The normal range for white blood cells is 4 to 10 billion per liter.
If the white blood cell count increases and exceeds 10 billion per liter, this condition is referred to as leukocytosis.
When leukocytosis is accompanied by fever, it most commonly indicates a bacterial infection.
During a bacterial infection, as pathogens invade the body, the body may respond to external stimuli, potentially causing the patient to develop a fever. In some cases, the body temperature may rise above 38 degrees Celsius (100.4 degrees Fahrenheit).
Based on the results of bacterial culture and antibiotic sensitivity testing, appropriate antibiotics should be selected for treatment.
Additionally, if leukocytosis and fever are present, further diagnostic tests such as peripheral blood smear and bone marrow aspiration may be necessary to rule out other conditions, including leukemia.
